What is "taccalonolide"

Taccalonolides are a class of microtubule-stabilizing agents isolated from Tacca chantrieri that has been shown to have selective cancer-fighting properties. Other examples of microtubule-stabilizing agents include taxanes and epothilones, both of which prevent cancer cells from dividing by interfering with tubulin. While taxanes like Paclitaxel and docetaxel have been used successfully against breast, ovarian, prostate, and non–small-cell lung cancers, intrinsic and acquired drug resistance limit their anticancer properties. Unlike taxanes, taccalonolides appear to work through a different mechanism of action that does not involve tubulin, although recently isolated taccalonolides AF and AJ have shown tubulin-interaction activity. The discovery of taccalonolides opens up new possibilities to treat cancer cells, especially ones that are taxane or epithilone resistant.
